Just want to monitor it when towing so I can see when the exhaust brake is working. Sometimes you can't even feel it.

Anyone on here familiar with the android app called torque pro? I'm trying to figure out what to enter for a custom pid for monitoring the turbocharger vain position. Anyone able to point me in the right direction? Thanks in advance

I had a upper a arm loose at the frame. Made a popping noise. Tightening it up fixed mine.

This is true. And they hate when you troubleshoot for them. The problem with this issue is at least on my truck was it never a daily occurrence. It usually did its thing in the summer and after the BCM got hot. Usually 30 or so minutes into a trip. Some days it didn't. So they'll say they could not duplicate it.

This is a normal occurrence with direct injection engines

You can. But I bet they tell you problem cannot be duplicated.

Possibly. But really. Getting to that ground is stupid easy.

My how to isn't duplicate. I put it in the other sections too. This is the how to. Please do not delete it.

That's a great idea

Essentially yes. Doesn't take to long to check it. I would look at it out if spite.

Mine did the same thing. Communication errors with the BCM. Due to the voltage drop. Basically the BCM was turning on and off essentially.

On the 1500 it does not run near the pedals. It goes from the BCM straight up to the top of the dash

Only way to tell is when summer hits. Higher temps make the BCM heat up more. After I had my BCM replaced it fixed the issue for a month then it came back. Honestly I would check that ground. It doesn't take long to get to it.

The Sierra trucks are doing it as well

You're welcome on the post. Believe me I was pissed when my truck did this. I love the truck to much to get rid of it and I love electronics and troubleshooting things. So glad my video and posts are helpful.

Ok let me introduce myself. My name is Tony Lester. So I have a 2014 silverado that I experienced a TON of funky electrical issues a few months ago. Had my head lights flickering, had stabilitrak errors, power steering errors, and the worst of all, the steering wheel jerking out of my hands. So after some looking around on youtube I found some videos from a guy named Robert Corona. So he had the exact same issues as my truck did. First thing his dealer did was replaced his BCM. So I did the same (mine was out of pocket because his was under warranty). My issue nor his went away. So next, he posted another video and a copy of his invoice from where they looked into his issue. They found that ground point named G218 had a "high resistance", but never went into detail on what this was. So after watching his videos My truck finally did the steering wheel jerk thing and I was fed up. Immediately, I started literally taking apart my dash, because I knew a ground had to be somewhere but I wasnt sure. All I had was a web page after hours of searching I had one crappy photo . as you can see It shows absolutely zero clues of where it actually is located. So the next day after more looking around and visiting my dealer I find out that it is on top of the dash, driver side, behind the speaker. So I go home and start putting my truck back together where I tore into it and went for the correct location. I then find this... Yep that would cause a "high resistance" alright. So I removed the nut and the ground then I trimmed the sound deadening material and put it back together. So far its been 8 months since I have did this and the truck is running like a champ. ZERO issues. Here is what I did to the material, as you can see I trimmed quite a bit... Also I decided to look on the other side of the dash to the ground G210 and cut it as well, It is NOT necessary to do this but I did anyway. Now on this next pic you can see the ground diagram for the G218 ground. This ground goes to several important and some not important components. It goes to the BCM, and steering angle sensor. That is why the wheel jerks like it does. When the BCM gets a "high resistance" on that ground it gets a voltage drop. When the BCM doesnt get full 12 volts it starts to heat up. When it heats up is when all these issues come up. Below are the ground diagrams.
